[0002] The limbs of a robot or robotic arm rotate through a rotating device, such as using a motor as a drive to rotate the rotating frame, thereby driving the rotation of the entire limb.

[0003] In the existing technology, due to the limited space in the robot or robotic arm, smaller motors are usually used. The output shaft of the motor is also smaller, and it is not easy to align the output shaft with the rotation shaft of the rotating frame, resulting in uncoordinated and unstable rotation of the rotating frame.

[0004] Therefore, existing technologies still need improvement and development. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an assembly method for a rotating device, which addresses the above-mentioned defects of the prior art. The method aims to solve the problem that the output shaft of the motor is not easily aligned with the rotating shaft of the rotating frame, resulting in uncoordinated and unstable rotation of the rotating frame.

[0043] To make the objectives, technical solutions, and advantages of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0044] Please also refer to Figures 1-7 The present invention provides some embodiments of a rotating device.

[0045] like Figures 1-2 As shown, the rotating device of the present invention includes: a mounting base 10, a folding motor 20, and a rotating frame 30; the rotating frame 30 has a shaft groove 31 for inserting the flat output shaft 21 of the folding motor 20; the mounting base 10 has two first through holes 11, two second through holes 12, and at least one third through hole 13; the rotating frame 30 has two first mounting holes 32; the folding motor 20 has two second mounting holes 22 and at least one third mounting hole 23; the line connecting the two first through holes 11 is orthogonal to the line connecting the two second through holes 12.

[0046] Specifically, the mounting base 10 is used to mount the folding motor 20 and the rotating frame 30. The folding motor 20 is fixed to the mounting base 10, and the rotating frame 30 rotates relative to the mounting base 10. A shaft groove 31 is formed on the rotating frame 30. The folding motor 20 has a flat output shaft 21, which has a flat section that mates with the groove wall of the shaft groove 31. There can be two flat sections, each facing one of the two groove walls of the shaft groove 31, and the flat sections can rest against the groove wall of the shaft groove 31. When the flat output shaft 21 rotates, it can drive the rotating frame 30 to rotate. A first through hole 11, a second through hole 12, and a third through hole 13 are formed on the mounting base 10. A first assembly hole 32 is formed on the rotating frame 30. The first assembly hole 32 is used to assemble a first assembly part 41. The first assembly hole 32 corresponds to the first through hole 11, and the first assembly part 41 passes through the first through hole 11 and the first assembly hole 32, thus achieving a rotatable connection between the mounting base 10 and the rotating frame 30. A second mounting hole 22 is formed on the folding motor 20 for mounting a second assembly 42. The second mounting hole 22 corresponds to the second through hole 12, and the second assembly 42 passes through both the second through hole 12 and the second mounting hole 22. A third mounting hole 23 is also formed on the folding motor 20 for mounting a third assembly 43. The third mounting hole 23 corresponds to the third through hole 13, and the third assembly 43 passes through both the third through hole 13 and the third mounting hole 23. The second assembly 42 and the third assembly 43 are used to achieve a fixed connection between the folding motor 20 and the mounting base 10.

[0047] There are two first through holes 11, and their axes are basically collinear. There are also two first mounting holes 32, and their axes are basically collinear. After the first assembly 41 is installed, the two first through holes 11 and the two first mounting holes 32 are all basically on the same straight line. There are two second through holes 12, and their axes are basically parallel to each other. There are also two second mounting holes 22, and their axes are basically parallel to each other. The axes of one second through hole 12 and one second mounting hole 22 are basically collinear, while the axes of the other second through hole 12 and the other second mounting hole 22 are basically on another straight line, and these two lines are basically parallel to each other. The line connecting the two first through holes 11 and the line connecting the two second through holes 12 are basically perpendicular to each other. This facilitates the collinearity of the axis of the flat output shaft 21 with the axis of the first through hole 11, resulting in a higher compatibility between the folding motor 20 and the rotating frame 30, and a smoother and more stable rotation of the rotating frame 30.

[0048] The mounting base 10 includes a base plate 101 and a vertical plate, the vertical plate being disposed on the base plate 101; the vertical plate includes two first vertical plates 102, each first vertical plate 102 having a first through hole 11. The vertical plate also includes a second vertical plate 103, the second vertical plate 103 having two second through holes 12. The vertical plate also includes a third vertical plate 104, the third vertical plate 104 having at least one third through hole 13.

[0049] In a preferred embodiment of the present invention, the midpoint of the line connecting the two second through holes 12 is located on the line connecting the two first through holes 11.

[0050] Specifically, the midpoint of the line connecting the two second through holes 12 is approximately located on the line connecting the two first through holes 11. The flat output shaft 21 is approximately located at the midpoint of the line connecting the two second mounting holes 22, which is also approximately located at the midpoint of the line connecting the two second through holes 12. This facilitates the alignment of the axis of the flat output shaft 21 with the axis of the first through hole 11. The line connecting the two second through holes 12 is roughly horizontal, i.e., parallel to the base plate 101.

[0051] In a preferred implementation of this invention, such as Figure 2 and Figure 6 As shown, the shaft groove 31 has openings on both sides, through which the flat output shaft 21 passes.

[0052] Specifically, openings are formed on the sidewalls on both sides of the shaft groove 31. These sidewalls are not corresponding to the flat position, and the openings allow the flat position output shaft 21 to pass through.

[0053] In a preferred implementation of this invention, such as Figure 2 , Figure 6 and Figure 7As shown, a clearance notch 34 is formed at the position corresponding to the opening on the rotating frame 30, and the clearance notch 34 avoids the second assembly 42.

[0054] Specifically, a clearance notch 34 is formed at the edge of the opening on the rotating frame 30, which avoids obstructing the second assembly 42. Because the folding motor 20 is relatively small, the distance between the second mounting hole 22 and the flat output shaft 21 is relatively short, and consequently, the distance between the second assembly 42 and the flat output shaft 21 is also relatively short. To prevent the rotating frame 30 from interfering with the assembly of the second assembly 42, a clearance notch 34 is formed on the rotating frame 30. When the clearance notch 34 on the rotating frame 30 rotates to the position of the second through hole 12, the second assembly 42 is inserted into the second through hole 12 and the second mounting hole 22 from the position of the clearance notch 34 without being interfered with by the rotating frame 30. There are two second through holes 12, and there can also be two clearance notches 34.

[0055] In a preferred implementation of this invention, such as Figures 6-7 As shown, a fourth mounting hole 33 is formed on the rotating frame 30, and the fourth mounting hole 33 communicates with the shaft groove 31.

[0056] Specifically, a fourth mounting hole 33 is formed on the rotating frame 30. The fourth mounting hole 33 communicates with the shaft groove 31, and the opening of the fourth mounting hole 33 is located on the groove wall of the shaft groove 31. The fourth mounting hole 33 is used to assemble the fourth assembly part 44.

[0057] In a preferred implementation of this invention, such as Figure 2 , Figure 6 and Figure 7 As shown, the fourth assembly 44 uses screws, and the fourth assembly hole 33 is a screw hole.

[0058] Specifically, the fourth assembly 44 uses a screw, the fourth assembly hole 33 is a screw hole, the screw and the screw hole form a threaded connection, and the screw can abut against the flat part of the flat output shaft 21, thereby pressing the flat output shaft 21.

[0059] In a preferred implementation of this invention, such as Figure 2 , Figure 6 and Figure 7 As shown, the first assembly 41 uses a threaded pin, and the first assembly hole 32 is a screw hole.

[0060] Specifically, the first assembly 41 uses a threaded pin, which has a threaded part and a shaft part. The threaded part has threads to facilitate threaded connection with the first assembly hole 32; the shaft part does not have threads to facilitate rotation of the shaft part in the first through hole 11.

[0061] In a preferred implementation of this invention, such as Figures 2-5 As shown, both the second assembly 42 and the third assembly 43 use screws, and both the second assembly hole 22 and the third assembly hole 23 are screw holes.

[0062] Specifically, the second mounting part 42 and the third mounting part 43 are both screws, and the second mounting hole 22 and the third mounting hole 23 are both screw holes, which facilitates fixing the folding motor 20 to the mounting base 10.

[0063] Based on the rotating device described in any of the above embodiments, the present invention also provides a preferred embodiment of the assembly method of the rotating device.

[0064] like Figure 8 As shown, the assembly method of the rotating device according to an embodiment of the present invention includes the following steps:

[0065] Step S100: Assemble the first assembly part into the first through hole and the first assembly hole to realize the rotatable connection between the rotating frame and the mounting base;

[0066] Step S200: Insert the flat output shaft into the shaft groove, and assemble the second assembly into the second through hole and the second assembly hole;

[0067] Step S300: Rotate the rotating frame to a preset angle and fix the flat output shaft to the shaft groove;

[0068] Step S400: Assemble the third assembly part into the third through hole and the third assembly hole to achieve a fixed connection between the folding motor and the mounting base.

[0069] Specifically, first, the rotating frame is mounted on the mounting base. The rotating component or mounting base is then moved until the positions of the first through hole and the first mounting hole correspond. Next, the first assembly part is passed through the second through hole and assembled into the second mounting hole, achieving a rotatable connection between the rotating frame and the mounting base. Then, the folding motor is installed. Since the folding motor is connected to both the mounting base and the rotating frame, a cross-assembly method is used. First, the flat output shaft is inserted into the shaft groove, and the second rotating component is installed. Then, the rotating frame is rotated to connect the flat output shaft to the shaft groove. Finally, the third assembly part is installed.

[0070] During the assembly of the second assembly, the first direction of the folding motor was calibrated using the second assembly. Then, the rotating frame was rotated, causing the flat output shaft to rotate, and the flat output shaft was fixed to the rotating frame. The second direction of the folding motor was calibrated using the rotating frame. Finally, the folding motor was fixed in place using the third assembly, so that the flat output shaft has good accuracy in both the first and second directions, and the axis of the flat output shaft is closer to coinciding with the axis of the first through hole. The rotation of the flat output shaft and the rotation of the rotating frame are more coordinated, smooth, and stable.

[0071] Step S200 specifically includes:

[0072] Step S210: Rotate the rotating frame so that the clearance notch is located at the position corresponding to the second through hole;

[0073] Step S220: Pass the second assembly through the second through hole from the position of the clearance notch and lock it into the second assembly hole.

[0074] Specifically, when installing the second assembly, the rotating bracket can be rotated to the position where the clearance notch corresponds to the second through hole, so that the second assembly can pass through the second through hole from the position of the clearance notch, and it is also convenient to use the corresponding tool (such as a screwdriver) to lock the second assembly into the second assembly hole.

[0075] The two second through holes are set horizontally. The clearance notch needs to be rotated to a horizontal position so that the clearance notch can correspond to the position of the second through holes, which will facilitate the installation of the second assembly.

[0076] Step S300 specifically includes:

[0077] Step S310: Assemble the fourth assembly part into the fourth assembly hole so that the fourth assembly part abuts against the flat output shaft.

[0078] Specifically, the flat output shaft can be initially fixed using the fourth mounting accessory. The fourth mounting accessory is fitted into the fourth mounting hole and abuts against the flat output shaft.

[0079] Step S300 specifically includes:

[0080] Step S320: The flat output shaft is fixedly connected to the groove wall of the shaft groove by welding.

[0081] Specifically, welding is further employed to fix the flat output shaft to the groove wall at its contact point. Welding is inconvenient when the clearance notch is horizontal; the rotating frame needs to be rotated to an upward position (rotation angle 80°~100°) for easier welding. Utilizing the clearance notch to horizontally align with the second through hole facilitates the installation of the second assembly. Rotation is required for welding, and it also facilitates alignment of the flat output shaft in two directions, bringing the axis of the flat output shaft closer to coincide with the axis of the first through hole.

[0082] It should be understood that the application of the present invention is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
